Abstract: A powertrain and a vehicle. The powertrain includes an enclosure, a separator, a motor, a first liquid return channel, and a second liquid return channel. The separator separates an interior of the enclosure into a first cavity and a second cavity. The motor is located in the first cavity. The first liquid return channel is located on an outer side of the enclosure and communicates with the first cavity and the second cavity. The second liquid return channel is located on the outer side of the enclosure and communicates with the first cavity and the second cavity. In the embodiments, with two liquid return channels provided, a liquid return requirement can be met when the powertrain is installed or disposed at any angle or used on a slope, improving adaptability and safety of the powertrain.

Abstract: A drive motor and a retarder in a powertrain meet a condition that a harmonic order of the drive motor is the same as a quantity of gear teeth of an input shaft gear in the retarder such that a frequency of an electromagnetic noise harmonic generated by the drive motor is the same as a frequency of a noise harmonic generated by the retarder. When the drive motor and the retarder are coupled using a connection structure, a phase of the electromagnetic noise harmonic generated by the drive motor differs from a phase of the noise harmonic generated by the retarder by a set angle.
